Microsoft (MSFT) on Tuesday announced that it has built one of the top five supercomputers in the world designed specifically for OpenAI. The company made the announcement during its Build developers conference, which is being held virtually rather than in person in Seattle where it is usually held each year. The supercomputer, Microsoft says, will be used to train OpenAI’s own artificial intelligence models. OpenAI, which was founded in 2015 and received initial funding from the likes of Elon Musk and Sam Altman. Musk has since left the company, while Altman is now its CEO. The company is working to create artificial general intelligence, or AI that is capable of outperforming humans, according to the group’s charter. The firm says its main concern is that such technologies benefit all of humanity, while ensuring its power doesn’t become concentrated in the hands of a few. The new supercomputer has an incredible 285,000 CPU cores, 10,000 graphics processing units, and 400 gigabits per second of connectivity for each GPU server. While the computer ranks in the top five of the most powerful machines in the world, Microsoft won’t say exactly where it falls on that list.
